Protein Structure
There are about 21,000 different kinds of human proteins. It is important to understand that the shape of a protein determines its functions. Proteins are made of long amino acid chains. The amino acids making up these chains are held together by peptide bonds. There are 20 different amino acids used to make these chains. Amino acids chains can be from 50 to thousands of amino acids long. The blood sugar regulating hormone is 55 amino acids long. The proteins in muscles are thousands of amino acids long. The order and number of the amino acids in the chain give the protein its shape. The amino acid chains fold into different shapes after they are made. These different shapes give each protein a different function. So, different arrangements of amino acids fold into different shapes giving proteins different functions.
